Abstract
Precision diagnosis is the keystone of clinical medicine. In East Asians, classical type 1 diabetes is uncommon in patients with youngonset diabetes diagnosed before age of 40, in whom a family history, obesity, and beta-cell and kidney dysfunction are key features. Young-onset diabetes affects one in five Asian adults with diabetes in clinic settings; however, it is often misclassified, resulting in delayed or non-targeted treatment. Complex aetiologies, long disease duration, aggressive clinical course, and a lack of evidence-based guidelines have contributed to variable care standards and premature death in these young patients. The high burden of comorbidities, notably mental illness, highlights the numerous knowledge gaps related to this silent killer. The majority of adult patients with youngonset diabetes are managed as part of a heterogeneous population of patients with various ages of diagnosis. A multidisciplinary care team led by physicians with special interest in young-onset diabetes will help improve the precision of diagnosis and address their physical, mental, and behavioral health. To this end, payors, planners, and providers need to align and re-design the practice environment to gather data systematically during routine practice to elucidate the multicausality of young-onset diabetes, treat to multiple targets, and improve outcomes in these vulnerable individuals.

Abstract
The incidence and prevalence of youth-onset type 2 diabetes mellitus (T2DM) and its complications are increasing worldwide. Youth-onset T2DM has been reported in all racial and ethnic groups, but Indigenous peoples and people of colour are disproportionately affected. People with youth-onset T2DM often have a more aggressive clinical course than those with adult-onset T2DM or those with type 1 diabetes mellitus. Moreover, the available treatment options for children and adolescents with T2DM are more limited than for adult patients. Intermediate complications of youth-onset T2DM, such as increased albuminuria, often develop in late childhood or early adulthood, and end-stage complications, including kidney failure, develop in mid-life. The increasing frequency, earlier onset and greater severity of childhood obesity in the past 50 years together with increasingly sedentary lifestyles and an increasing frequency of intrauterine exposure to diabetes are important drivers of the epidemic of youth-onset T2DM. The particularly high risk of the disease in historically disadvantaged populations suggests an important contribution of social and environmental factors, including limited access to high-quality health care, healthy food choices and opportunities for physical activity as well as exposure to stressors including systemic racism and environmental pollutants. Understanding the mechanisms that underlie the development and aggressive clinical course of youth-onset T2DM is key to identifying successful prevention and management strategies.

Abstract
OBJECTIVE Neutrophil gelatinase-associated lipocalin (NGAL) is one of the new biomarkers for detecting acute renal injury. There are studies showing the relationship between NGAL and renal injury in obese children. The aim of this study was to investigate whether urinary levels of NGAL, kidney injury molecule-1, and serum cystatin C are increased in insulin resistance (IR) patients before the development of diabetes. METHODS Cross-sectional, case-controlled study that included non-diabetic obese children and adolescent patients with IR and a non-diabetic obese control group with no IR, who attended a tertiary center pediatric endocrinology outpatient clinic between 2016-2018. Those with diabetes mellitus and/or known renal disease were excluded. NGAL and creatinine (Cr) levels were evaluated in the morning spot urine from all participants. Serum renal function was evaluated. RESULTS Thirty-six control and 63 IR patients were included in the study, of whom 68 (68.7%) were girls. The mean age of all participants was 13.12±2.64 years and no statistically significant difference was found between the two groups in terms of age or gender distribution. Median (range) spot urinary NGAL (u-NGAL) values in the IR group were significantly higher at 26.35 (7.01-108.7) ng/mL than in the control group at 19.5 (3.45-88.14) ng/mL (p=0.018). NGAL/Cr ratio was also significantly higher in the IR group compared to the control group (p=0.018). CONCLUSION Obese pediatric patients with IR were shown to have elevated levels of u-NGAL, a marker of renal injury. u-NGAL examination may show early renal injury before development of diabetes.

Abstract
Background Observational studies suggested that tobacco smoking was associated with diabetic nephropathy (DN). However, the results were conflicting and inconsistent. In the study, we performed a meta-analysis to assess the relationship between tobacco smoking and the development of DN. Materials and methods We searched in PubMed, Embase, Web of Science and the Cochrane Library (CENTRAL) from database inception until Mar 8, 2018, and updated our search on May 1, 2018. We screened the reference lists of the retrieved articles. Only original prospective cohort studies which have investigated the association between smoking and DN incidence or its progression were included. Pooled HRs and 95% confidence intervals (CIs) were calculated using a random effects model. Results A total of 9 prospective cohort studies were identified, including more than 203337 participants. Compared with those of no smoking, smoking participants increased the risk of developing DN (HR = 1.07, 95% CI: 1.01–1.13, P = 0.01). The subgroup analysis showed that the current and total smoking may increase the risk of DN, but these results did not reach statistical significance (current: HR = 1.69, 95% CI = 0.79–3.64, p = 0.17; total: HR = 1.17, 95% CI = 0.97–1.41, p = 0.10), whereas former smoking significantly increased the risk of DN (HR = 1.04, 95% CI = 1.03–1.05, p<0.001). Compared with no-smokers, smokers showed an elevated risk of developing DN (HR = 1.05; 95% CI, 1.00–1.11, P = 0.05). In patients with T2DM, those who smoked were at an increased risk of developing DN, as compared to those who had never smoked (HR = 1.05; 95% CI, 1.00–1.11, P = 0.05). However, compared to no smoking, smoking did not increase the risk of DN development in patients with T2DM (HR = 1.15; 95% CI, 0.9–1.47, P = 0.25). Univariate and multivariate meta-regression did not find any confounding factors. No publication bias was found in the meta-analysis. Conclusions The present study highlighted that smoking was an independent risk factor for DN, especially in patients with T1DM. This is the first meta-analysis of prospective cohort studies to discuss the relationship between smoking and DN.

Abstract
PURPOSE OF REVIEW Compared to adult-onset type 2 diabetes (T2D), youth with T2D have a more aggressive phenotype with greater insulin resistance (IR), more rapid β cell decline, and higher prevalence of diabetic kidney disease (DKD). RECENT FINDINGS Hyperfiltration is common in youth with T2D and predicts progressive DKD. Hyperfiltration is a consequence of early changes in intrarenal hemodynamic function, including increased renal plasma flow (RPF) and glomerular pressure. Girls with T2D are disproportionally affected by DKD, with a 3-fold greater risk of developing hyperfiltration over 5 years compared to boys. Despite the high prevalence and gravity of DKD in youth-onset T2D, widely effective therapeutic options are lacking. In this review, we focus on pathophysiology underlying early DKD in T2D and sex differences and summarize promising novel medical therapies and bariatric surgery.

Abstract
BACKGROUND The aim of this study was to assess the effects of smoking on albuminuria risk in adults with type 2 diabetes mellitus (T2DM). METHODS A literature search was conducted using MEDLINE, EMBASE, and China National Knowledge Infrastructure from the established date to October 2017. Summary relative risks (SRR) and 95% confidence intervals (CI) were computed utilizing a random effect inverse variance method. RESULTS This meta-analysis included a total of 19 relevant observational studies (four prospective cohort, seven case-control, and eight cross-sectional studies), reporting 105,031 participants and 23,366 albuminuria events. Compared with never-smokers with T2DM, the SRRs of albuminuria were 1.43 (95% CIs 1.27-1.61) for ever-smokers, 2.61 (95% CIs 1.86-3.64) for current smokers, and 1.86 (95% CIs 1.37-2.52) for former smokers. Considerable heterogeneity was observed among these studies, and study design was a significant modifier for this association. There were significantly elevated risk associations for microalbuminuria (SRRs = 1.24, 95% CIs 1.05-1.46) and for macroalbuminuria (SRRs = 1.65, 95% CIs 1.03-2.66), respectively. CONCLUSIONS Our systematic review and meta-analysis indicates that cigarette smoking might be a potential factor for the development of albuminuria in adults with T2DM. Future studies are required to investigate the association between smoking cessation and intensity and incident albuminuria in adults with T2DM.

Abstract
BACKGROUND Diabetic kidney disease is a major cause of premature mortality in type 2 diabetes mellitus (T2DM). Worsening insulin sensitivity independent of glycemic control may contribute to the development of diabetic kidney disease. We investigated the longitudinal association of insulin sensitivity with hyperfiltration and increased albumin excretion in adolescents with T2DM. STUDY DESIGN Observational prospective cohort study. SETTING & PARTICIPANTS 532 TODAY (Treatment Options for Type 2 Diabetes in Adolescents and Youth) participants aged 12 to 17 years with T2DM duration less than 2 years at baseline. The TODAY Study was a multicenter randomized clinical trial that examined the efficacy of 3 treatment regimens (metformin monotherapy, metformin plus rosiglitazone, or metformin plus an intensive lifestyle intervention program) to achieve durable glycemic control. PREDICTORS Natural log-transformed estimated insulin sensitivity (reciprocal of fasting insulin), hemoglobin A1c concentration, age, race-ethnicity, treatment group, body mass index, loss of glycemic control, and hypertension. OUTCOMES Hyperfiltration was defined as 99th percentile or higher of estimated glomerular filtration rate (≥140mL/min/1.73m2) when referenced to healthy adolescents (NHANES 1999-2002) and albumin-creatinine ratio ≥ 30μg/mg at 3 consecutive annual visits. RESULTS Hyperfiltration was observed in 7.0% of participants at baseline and in 13.3% by 5 years, with a cumulative incidence of 5.0% over 5 years. The prevalence of increased albumin excretion was 6% at baseline and 18% by 5 years, with a cumulative incidence of 13.4%. There was an 8% increase in risk for hyperfiltration per 10% lower estimated insulin sensitivity in unadjusted and adjusted models (P=0.01). Increased albumin excretion was associated with hemoglobin A1c concentration, but not estimated insulin sensitivity. LIMITATIONS Longer follow-up is needed to capture the transition from hyperfiltration to rapid glomerular filtration rate decline in youth-onset T2DM. CONCLUSIONS Lower estimated insulin sensitivity was associated with risk for hyperfiltration over time, whereas increased albumin excretion was associated with hyperglycemia in youth-onset T2DM.

Smoking and the risk of diabetic nephropathy in patients with type 1 and type 2 diabetes: a meta-analysis of observational studies. Oncotarget 2017; 8:93209-93218. [PMID: 29190990 PMCID: PMC5696256 DOI: 10.18632/oncotarget.21478] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2017] [Accepted: 09/21/2017] [Indexed: 12/21/2022] Open
Abstract
Background Conflicting evidence exists for observational studies on whether tobacco smoking is a risk factor for diabetic nephropathy (DN) in patients with type 1 (T1DM) and type 2 diabetes mellitus (T2DM). In this meta-analysis, we aimed to assess the effects of tobacco smoking on the development of DN. Materials and Methods We searched MEDLINE and EMBASE databases from their inception to March 31st, 2017 for cross-sectional, case-control, and prospective cohort studies. We screened reference lists of retrieved articles. Summary relative risks (SRRs) and 95% confidence intervals (CIs) were calculated using a random-effects model. Results A total of nineteen observational studies (1 case-control, 8 cross-sectional and 10 prospective cohort studies) were identified, involving more than 78,000 participants and a total of 17,832 DN cases. Compared with never-smokers, there was an augmented SRR (95% CI) of DN in ever-smokers in patients with T1DM (1.31 [1.06–1.62]; P = 0.006) and T2DM (1.44 [1.24–1.67]; P < 0.001), respectively. In patients with T1DM, the SRR (95% CI) was 1.25 (0.86–1.83) for microalbuminuria only, 1.27 (1.10–1.48) for macroalbuminuria only, and 1.06 (0.97–1.15) for end-stage renal disease (ESRD). In patients with T2DM, the SRR (95% CI) associated with ever smoking was 1.46 (0.94–2.26) for microalbuminuria only, 1.72 (1.04–2.84) for macroalbuminuria only, and 1.10 (0.36–3.33) for ESRD. Conclusions Our meta-analysis suggests evidence for cigarette smoking as an independent risk factor for the development of DN in patients with both T1DM and T2DM.

Abstract
BACKGROUND The positive impact of Roux-en-Y gastric bypass (RYGB) on metabolic syndrome and glycemic control has been proven in obese patients. One anastomosis gastric bypass (OAGB) is a simple, effective and easy to learn procedure. OAGB provides encouraging results for the treatment of diabetes obese patients, but does it have the ability to be an alternative procedure to RYGB in the treatment of these patients? The aim of this study is to evaluate the outcomes of OAGB on diabetic obese patients at the bariatric centre of our university hospital. By extension, we evaluated the possibility of BMI and the preoperative antidiabetic medication usage to be predictive factors for postoperative diabetes resolution. METHODS This is a retrospective single-centre study of 472 diabetic patients who underwent OAGB from November 2009 to December 2015. All patients were followed-up for at least 1 year, and up to 3 years, where available. Weight, HbA1c, and anti-diabetic medications were recorded at baseline, 3, 6, 12, 24 and 36 months. RESULTS A total of 472 patients have been followed-up for 1 year and 361 for 3 years. The mean BMI decreased from 46.8 ± 7.2 to 29.5 ± 2.8 kg/m2 and HbA1c from 9.6 ± 1.3 to 5.7 ± 1.5% at the 12-month follow-up. At the 3-year follow-up, the mean BMI was 32.1 ± 3.3 and HbA1c mean was 5.8 ± 0.9%. Diabetes remission was achieved by 84.1% of patients. CONCLUSIONS OAGB can be an excellent alternative to RYGB for the treatment of diabetes and obesity. Pre-operative medications may be used to predict postoperative diabetes remission, but not BMI.

Abstract
Type 2 diabetes mellitus (T2DM) is a current global health priority and Asia is the epicenter of this epidemic disease. Unlike in the west, where older population is most affected, the burden of diabetes in Asian countries is disproportionately high in young to middle-age adults. The incidence of diabetic nephropathy is alarmingly high in patients with early onset T2DM, especially in those with poor glycemic control. How to control this chronic and debilitating disease is currently a very important health issue in Asia. Bariatric surgery has proven successful in treating not just obesity but also T2DM in morbid obese patients (body mass index [BMI] >35 kg/m²). Gastrointestinal metabolic surgery recently has been proposed as a new treatment modality for obesity related T2DM for patients with BMI <35 kg/m². Many studies from Asia reported promising results of metabolic surgery to treat obese patients with T2DM which is not well controlled. It has been demonstrated that changes in gastrointestinal hormone secretion after gastrointestinal surgery would favor an early improvement of T2DM in Asians. New procedures have also been designed and proposed specifically for the treatment of diabetes in Asia. This article examines clinical trial data and accepted algorithms with a view toward elucidating the application of metabolic surgery for the treatment of T2DM in the Asia. We propose a systematic approach to surgical treatment, addressing current evidences, patient selection, procedure of choice, and timing and guideline for new procedures.

Abstract
BACKGROUND Urinary myo-inositol (UMI) level is elevated in adult diabetic patients, and also increases after glucose loading. However, the relationship between UMI and plasma glucose levels in children is unknown. We aimed to assess whether UMI is a practical marker for glucose intolerance in children or not. METHODS In Study 1 (328 schoolchildren), fasting and postprandial UMI were measured, with ΔUMI defined as the difference between fasting and postprandial UMI levels. In Study 2, oral glucose tolerance tests and UMI measurements were conducted in 18 children with suspected having diabetes. RESULTS For Study 1, ΔUMI was observed [-0.65 (-3.9, 1.35) mg/g creatinine]. For Study 2, children with diabetes or impaired glucose tolerance had a significantly higher ΔUMI than children with normal glucose tolerance. CONCLUSIONS These studies demonstrated the normal range of UMI in children and possibility of a novel biomarker for early detection of glucose intolerance in children.

Abstract
Diabetic kidney disease (DKD) is the leading cause of end-stage renal disease (ESRD) and dialysis in the Western world. Early DKD, including microalbuminuria and renal hyperfiltration, is common in adolescents with type 2 diabetes (T2D). Furthermore, youth-onset T2D carries a higher risk of progressive DKD than adult-onset T2D of similar diabetes duration. DKD is characterized by a long clinically silent period without signs of disease. Therefore, a major challenge in preventing DKD is the difficulty in identifying high-risk T2D patients at an early stage. The Type 2 Diabetes in Adolescents and Youth (TODAY) study demonstrated a high initial prevalence that increased over time, irrespective of treatment arm. This key observation underscores the importance of discovering new therapeutic targets to supplement conventional management, in order to reduce DKD risk. In this review, we focus on early DKD in T2D and summarize potential novel biomarkers and therapeutic targets.

Abstract
BACKGROUND DATA Bariatric/metabolic surgery has been proposed for the treatment of inadequately controlled type 2 diabetes mellitus (T2DM) in obese patients. However, prediction on successful long-term remission of T2DM after metabolic surgery has not been clearly studied. Our objectives were to evaluate rates of long-term remission of T2DM after metabolic surgery and determine the independent predictors of remission. METHODS Outcomes of 157 patients who underwent metabolic surgery between 2006 and 2009 and who had complete 5-year follow-up data were assessed. Prolonged complete remission was defined as glycated hemoglobin (HbA1c) less than 6 % without diabetes medication up to 5 years. Predictors of prolonged remission studies included patient characteristics such as glucose level, HbA1c, body weight, waist circumference, blood pressure, total cholesterol, LDL, triglyceride, uric acid, AST, alanine transaminase (ALT), albumin, insulin, C-peptide, iron, calcium, complete blood cell count, the ABCD score (a multidimensional grading system composed of age, body mass index (BMI), C-peptide levels, and duration of T2DM), and postoperative weight loss. RESULTS At 5 years after surgery, the weight loss was 27.1 % and the mean BMI decreased from 39.8 to 28.8 kg/m(2). The mean HbA1c decreased from 8.3 to 6.0 %. A significant number of patients had improvement in their glycemic control, including 97 (71.3 %) patients who had complete remission (HbA1c < 6.0 %), 27 (19.9 %) partial remission (HbA1c < 6.5 %), and 12 (8.8 %) improved condition (HbA1c < 7 %). In univariate analysis, patients with prolonged T2DM remission after surgery were younger and heavier; had a wider waist, higher C-peptide, shorter duration of T2DM, higher liver enzyme, higher insulin resistance, higher C-peptide level, and higher white blood cell count; were taking smaller insulin dosage; had higher ABCD score; and had greater weight loss than those without remission. Multivariate logistical regression analyses showed that the ABCD score and weight loss were the only predictors of remission after metabolic surgery. CONCLUSIONS Metabolic surgery is a treatment option for patients with obesity and T2DM. Baseline ABCD score and weight loss have a major influence on outcome.

Abstract
BACKGROUND DiaRem score consists in preoperative model for predicting remission of type 2 diabetes mellitus in obese patients who underwent gastric bypass. AIM To evaluate the applicability of DiaRem comparing the scores obtained preoperatively with remission of T2DM after surgery. METHOD Preoperative parameters such as age, use of insulin, oral hypoglycemic agents and glycated hemoglobin, were retrospectively evaluated in diabetic patients undergoing gastric bypass during the period between July 2012 to July 2013. Through these data the DiaRem score were applied. The results of fasting blood glucose and glycated hemoglobin were requested prospectively. RESULTS Were selected 70 patients; the remission of T2DM after surgery was found in 42 (60%) and no remission in 28 (40%). Checking the final score, it was observed that: from 0 to 2 points, 94.1% of patients remitted completely; between 3 and 7 had remission in 68.9%, of which 42.8% complete; from 8 to 12, 57.1% achieved complete remission; between 13 to 17, 87.5% did not achieve remission and was not seen this complete remission group; between 18 to 22, 88.9% were not remitted. CONCLUSION The DiaRem score showed appropriate tool to assess remission of T2DM in obese patients who will undergo gastric bypass.

Abstract
China has a large burden of diabetes: in 2013, one in four people with diabetes worldwide were in China, where 11·6% of adults had diabetes and 50·1% had prediabetes. Many were undiagnosed, untreated, or uncontrolled. This epidemic is the result of rapid societal transition that has led to an obesogenic environment against a backdrop of traditional lifestyle and periods of famine, which together puts Chinese people at high risk of diabetes and multiple morbidities. Societal determinants including social disparity and psychosocial stress interact with factors such as low-grade infection, environmental pollution, care fragmentation, health illiteracy, suboptimal self-care, and insufficient community support to give rise to diverse subphenotypes and consequences, notably renal dysfunction and cancer. In the China National Plan for Non-Communicable Disease Prevention and Treatment (2012-15), the Chinese Government proposed use of public measures, multisectoral collaborations, and social mobilisation to create a health-enabling environment and to reform the health-care system. While awaiting results from these long-term strategies, we advocate the use of a targeted and proactive approach to identify people at high risk of diabetes for prevention, and of private-public-community partnerships that make integrated care more accessible and sustainable, focusing on registry, empowerment, and community support. The multifaceted nature of the societal and personal challenge of diabetes requires a multidimensional solution for prevention in order to reduce the growing disease burden.

Abstract
Early onset type 2 diabetes mellitus (T2DM) is increasingly prevalent with a significant impact on the individual, healthcare service delivery and planning. The individuals are likely to be obese, lead a sedentary lifestyle, have a strong family history of T2DM, be of black and minority ethnic (BME) origin and come from a less affluent socioeconomic group. They have a heightened risk of developing microvascular and macrovascular complications, often at an earlier stage and with greater frequency than seen in type 1 diabetes. As such, early and aggressive risk factor management is warranted. Early onset T2DM is complex and impacts on service delivery with a need for multidisciplinary care of complications and comorbidities', in addition to adequate educational and psychological support. This review on the impact of early onset T2DM provides the latest insights into this emerging epidemic.

Abstract
The occurrence and progression of nephropathy associated with early onset type 2 diabetes (T2D) is a consequence of the ongoing epidemic of childhood obesity. Minimal evidence regarding treatment effectiveness of renovascular comorbidities in youth with early onset T2D is available, due to the relatively recent emergence of T2D in youth and young adults. Extrapolation of adult therapy guidelines is not an ideal approach to making therapeutic decisions in this population. Evolving management and intervention strategies are based on accumulating longitudinal data from cohorts of well characterized youth and young adults with T2D. The degree of similarity in histologic findings and disease specific characteristics of kidney disease in patients with early onset T2D and albuminuria compared with affected adults is not well characterized. Early aggressive therapies to minimize the impact of nephropathy are indicated as the evidence for best therapies in youth with T2D are further explored.

Abstract
OBJECTIVE To evaluate the risk of complications in youth with type 2 diabetes. RESEARCH DESIGN AND METHODS Population-based cohorts of 342 youth (1-18 years of age) with prevalent type 2 diabetes, 1,011 youth with type 1 diabetes, and 1,710 nondiabetic control youth were identified between 1986 and 2007 from a clinical registry and linked to health care records to assess long-term outcomes using ICD-9CM and ICD-10CA codes. RESULTS Youth with type 2 diabetes had an increased risk of any complication (hazard ratio 1.47 [95% CI 1.02-2.12]). Significant adverse clinical factors included age at diagnosis (1.08 [1.02-2.12]), HbA1c (1.06 [1.01-1.12]), and, surprisingly, renin-angiotensin-aldosterone system (RAAS) inhibitor use (1.75 [1.27-2.41]). HNF-1α G319S polymorphism was protective in the type 2 diabetes cohort (0.58 [0.34-0.99]). Kaplan-Meier statistics revealed an earlier diagnosis of renal and neurologic complications in the type 2 diabetes cohort, manifesting within 5 years of diagnosis. No difference in retinopathy was seen. Cardiovascular and cerebrovascular diseases were rare; however, major complications (dialysis, blindness, or amputation) started to manifest 10 years after diagnosis in the type 2 diabetes cohort. Youth with type 2 diabetes had higher rates of all outcomes than nondiabetic control youth and an overall 6.15-fold increased risk of any vascular disease. CONCLUSIONS Youth with type 2 diabetes exhibit complications sooner than youth with type 1 diabetes. Younger age at diagnosis is potentially protective, and glycemic control is an important modifiable risk factor. The unexpected adverse association between RAAS inhibitor use and outcome is likely a confounder by indication; however, further evaluation in young people is warranted.

Abstract
In an open-label, parallel-group study involving 16 patients (8 with severely reduced renal function, 8 with end-stage renal disease needing hemodialysis), the effect of renal function on the pharmacokinetics, metabolism, and safety and of alpha-lipoic acid (thioctic acid) was evaluated by comparing the pharmacokinetic parameters with those of a reference group of 8 healthy subjects. Alpha-lipoic acid 600 mg was administered orally once daily for 4 days, and the pharmacokinetic parameters were measured on days 1 and 4. The mean percentage of the administered dose excreted in urine as parent compound was 0.2 and 0.05 in healthy subjects and subjects with severely reduced renal function, respectively. Assuming a bioavailability of 30%, this represents 0.67% and 0.17% of the bioavailable amount of alpha-lipoic acid, respectively. The percentage of total urinary recovered amounts of alpha-lipoic acid and 5 of its metabolites was 12.0 on both days. The respective values for patients with severe kidney damage were 5.2% (day 1) and 6.4% (day 4). The total percentage of the administered dose removed by hemodialysis was 4.0 in patients with end-stage renal disease. Renal clearance of alpha-lipoic acid and its major metabolites, 6,8-bismethylthio-octanoic acid, 4,6-bismethylthio-hexanoic acid and 2,4-bismethylthio-butanoic acid, were significantly decreased in subjects with kidney damage compared to the reference group. Apparent total clearance of alpha-lipoic acid was poorly correlated with creatinine clearance. There is strong evidence that alpha-lipoic acid is mainly excreted by nonrenal mechanism or further degraded to smaller units in the catabolic process. The significantly increased area under the curve values of 4,6-bismethylthio-hexanoic acid and half-lives of 2,4-bismethylthio-butanoic acid on both days in patients with severely reduced function and end-stage renal disease were not considered to be clinically relevant. Although trough levels of both metabolites tend to increase slightly in these subjects, no accumulation effects were detected. We conclude that the pharmacokinetics of alpha-lipoic acid are not influenced by creatinine clearance and are unaffected in subjects with severely reduced kidney function or end-stage renal disease. Hemodialysis did not significantly contribute to the clearance of alpha-lipoic acid. Hence, dose adjustment of alpha-lipoic acid is not necessary in patients with renal dysfunction.

Abstract
Youth-onset type 2 diabetes has emerged as a significant public health concern for American Indians and Alaska Natives. Data from the National Institutes of Health longitudinal epidemiological study among the Pima Indians of southern Arizona and the Indian Health Service continue to document a rising incidence and prevalence of type 2 diabetes among American Indian and Alaska Native youth. Although national trends related to lack of physical activity and to unhealthy nutrition behaviors have contributed to the epidemic, the adverse conditions created by poverty, social injustice, trauma, and cultural disruption are also important in understanding the underlying causes for this public health crisis. This adverse environment is likely to provide little support for healthy nutrition and physical activity behaviors as well as other diabetes self-care behaviors. Known risk factors from the Pima Indian studies, such as intrauterine exposure to diabetes, bottle-feeding, and obesity, provide a basis for worthwhile intervention strategies. In this article, the author will review the current literature on the epidemiology of youth-onset type 2 diabetes among American Indians and Alaska Natives, discuss causes for the diabetes epidemic among American Indians and Alaska Natives, review risk factors for youth-onset type 2 diabetes in this population, and share promising youth physical activity promotion programs created and implemented specifically for American Indian and Alaska Native youth. However, more research on interventions to address the Native communities' psychosocial issues and concerns around youth-onset type 2 diabetes is urgently needed.

Predicting success of metabolic surgery: age, body mass index, C-peptide, and duration score. Surg Obes Relat Dis 2012; 9:379-84.

Abstract
BACKGROUND Surgery is the most effective treatment of morbid obesity and leads to dramatic improvements in type 2 diabetes mellitus (T2DM). Gastrointestinal metabolic surgery has been proposed as a treatment option for T2DM. However, a grading system to categorize and predict the outcome of metabolic surgery is lacking. The study setting was a tertiary referral hospital (Taoyuan City, Taoyuan County, Taiwan). METHODS We first evaluated 63 patients and identified 4 factors that predicted the success of T2DM remission after bariatric surgery in this cohort: body mass index, C-peptide level, T2DM duration, and patient age. We used these variables to construct the Diabetes Surgery Score, a multidimensional 10-point scale along which greater scores indicate a better chance of T2DM remission. We then validated the index in a prospective collected cohort of 176 patients, using remission of T2DM at 1 year after surgery as the outcome variable. RESULTS A total of 48 T2DM remissions occurred among the 63 patients and 115 remissions (65.3%) in the validation cohort. Patients with T2DM remission after surgery had a greater Diabetes Surgery Score than those without (8 ± 4 versus 4 ± 4, P < .05). Patients with a greater Diabetes Surgery Score also had a greater rate of success with T2DM remission (from 33% at score 0 to 100% at score 10); A 1-point increase in the Diabetes Surgery Score translated to an absolute 6.7% in the success rate. CONCLUSION The Diabetes Surgery Score is a simple multidimensional grading system that can predict the success of T2DM treatment using bariatric surgery among patients with inadequately controlled T2DM.

Abstract
Associations of BMI with body composition and health outcomes may differ between Asian and European populations. Asian populations have also been shown to have an elevated risk of type 2 diabetes, hypertension, and hyperlipidemia at a relatively low level of BMI. New surgical indication for Asian patients should be discussed by the expert of this field. Forty-four bariatric experts in Asia-Pacific and other regions were chosen to have a voting privilege for IFSO-APC Consensus at the 2nd IFSO-APC Congress. A computerized audience-response voting system was used to analyze the agreement with the sentence of the consensus. Of all delegates, 95% agreed with the necessity of the establishment of IFSO-APC consensus statements, and 98% agreed with the necessity of a new indication for Asian patients. IFSO-APC Consensus statements 2011. Bariatric surgery should be considered for the treatment of obesity for acceptable Asian candidates with BMI ≥ 35 with or without co-morbidities. Bariatric/GI metabolic surgery should be considered for the treatment of T2DM or metabolic syndrome for patients who are inadequately controlled by lifestyle alternations and medical treatment for acceptable Asian candidates with BMI ≥ 30. The surgical approach may be considered as a non-primary alternative to treat inadequately controlled T2DM, or metabolic syndrome, for suitable Asian candidates with BMI ≥ 27.5. Other eight sentences are agreed with by majority of the voting delegates to form IFSO-APC consensus statements. This will help to make safe and wholesome the progress of bariatric and metabolic surgery in Asia.

Abstract
OBJECTIVE To evaluate renal outcomes and survival in youth with type 2 diabetes (T2DM) versus type 1 diabetes (T1DM) versus nondiabetic control subjects. RESEARCH DESIGN AND METHODS In total, 342 prevalent youth (aged 1-18 years) with T2DM, 1,011 youth with T1DM, and 1,710 control subjects identified from 1986 to 2007 were anonymously linked to health care records housed at the Manitoba Centre for Health Policy to assess long-term outcomes using ICD codes. RESULTS Youth with T2DM were found to have a fourfold increased risk of renal failure versus youth with T1DM. Risk factors associated with renal failure were renin angiotensin aldosterone system inhibitor use and albuminuria in adolescence. Compared with control subjects (age, sex, and postal code matched), youth with T2DM had a 23-fold increased risk of renal failure and a 39-fold increased risk of dialysis. Kaplan-Meier survival at 10 years was 91.4% in the type 2 diabetic group versus 99.5% in the type 1 diabetic group (P < 0.0001). Renal survival was 100% at 10 years in both groups. It decreased to 92.0% at 15 years and 55.0% at 20 years in the type 2 diabetic group but remained stable in the type 1 diabetic group (P < 0.0001). CONCLUSIONS Youth with T2DM are at high risk of adverse renal outcomes and death. Albuminuria and angiotensin aldosterone system inhibitor use, which may be a marker of severity of disease, are associated with poor outcomes in early adulthood.

Abstract
Asia bears the world's greatest burden of type 2 diabetes (T2DM) and prevalence is increasing rapidly. Compared to other races, Asians develop T2DM younger, at a lower degree of obesity, suffer longer from its complications and die earlier. Curbing this epidemic requires an integrated, risk-based, and multidisciplinary approach. Inadequately managed T2DM has macrovascular and microvascular sequelae, Asians with T2DM being particularly susceptible to diabetic nephropathy. Earlier and more intensive monitoring and management of risk factors are required, especially for patients with, or at risk of, renal impairment. Particular challenges of T2DM management in Asia include: lack of access to specialist healthcare, insufficient clinical evaluation and delayed diagnosis. As in Caucasians, conventional treatment modalities are limited by deteriorating glycaemic control with disease progression and there is an unmet need for efficacious, safe, cost-effective and convenient pharmacotherapies for treating different stages of T2DM and preventing its complications, particularly in high-risk patients. There is a trend towards increasing use of DPP-IV inhibitors, which are no less efficacious and safe in Asians than Caucasians and may have some advantages over existing oral antidiabetic agents, particularly for certain high-risk groups. Such agents may play a significant future role in the management of T2DM.

Abstract
BACKGROUND Most morbidly obese patients who undergo gastric bypass experience rapid remission of type 2 diabetes mellitus (T2DM) but the response in non-morbidly obese patients is not clear. This trial prospectively assessed the effect of diabetes remission, glucose metabolism, and the serial changes of insulin secretion after gastric bypass in inadequately controlled T2DM patients with a BMI of 23-35 kg/m(2). METHODS A total of 62 consecutive patients with T2DM and a BMI of 23-35 kg/m(2) underwent gastric bypass. Data were prospectively collected before surgery and 1, 4, 12, 26, and 52 weeks and 2 years after surgery. Insulin secretion was measured by insulinogenic index and area under the curve (AUC) during a standard oral glucose tolerance test (OGTT). Remission of type 2 diabetes was defined as fasting glucose level <110 mg/dl and HbA1c <6.0% without any glycemic therapy. RESULTS Of the 62 patients, 24 were men and 38 were women (age 43.1 ± 10.8 years). Their preoperative characteristics were as follows: BMI 30.1 ± 3.3 kg/m(2), waist circumference 99.6 ± 9.6 cm, C-peptide 3.1 ± 1.4 ng/ml, and duration of T2DM 5.4 ± 5.1 years. The mean BMI decreased postoperatively to 22.6 ± 2.3 kg/m(2) in 1 year and 23.0 ± 2.7 kg/m(2) in 2 years. The mean HbA1c decreased from 9.7 ± 1.9% to 5.8 ± 0.5% in 1 year and 5.9 ± 0.5% in 2 years. Complete remission of T2DM was achieved in 57% in 1 year and 55% in 2 years after surgery. Before surgery, the OGTT test showed a blunted insulin secretion pattern with an insulinogenic index of 0.1 ± 0.2 and AUC of 2,324 ± 1,015 μIU min/ml. In 1 week after surgery, the insulinogenic index increased to 0.16 and AUC decreased to 1,366 μIU min/ml along with a rapid drop of insulin resistance. The insulinogenic index and AUC gradually increased to 0.27 and 3,220, respectively, 1 year after surgery and remained stable up to 2 years with a very low insulin resistance. CONCLUSIONS Laparoscopic gastric bypass facilitates immediate improvement in the glucose metabolism of inadequately controlled non-severe obese T2DM patients, and the benefit is sustained up to 2 years after surgery. The benefit is regulated by the decrease in insulin resistance, increase in early insulin response, and total insulin secretion to glucose load.

Abstract
Youth onset type 2 diabetes (T2DM) continues to increase worldwide, concomitant with the rising obesity epidemic. There is evidence to suggest that youth with T2DM are affected by the same comorbidities and complications as adults diagnosed with T2DM. This review highlights specifically the kidney disease associated with youth onset T2DM, which is highly prevalent and associated with a high risk of end-stage kidney disease in early adulthood. A general understanding of this complex disease by primary care providers is critical, so that at-risk individuals are identified and managed early in the course of their disease, such that progression can be modified in this high-risk group of children and adolescents. A review of the pediatric literature will include a focus on the epidemiology, risk factors, pathology, screening, and treatment of kidney disease in youth onset T2DM.

Abstract
BACKGROUND Gastrointestinal metabolic surgery has been proposed for the treatment of not well-controlled type 2 diabetes mellitus (T2DM) patients with a body mass index (BMI) <35 kg/m(2). This study aims to describe recent experience with surgical treatment of T2DM in Asian centers. METHODS Patients aged 20 to 70 years with not well-controlled T2DM [glycated hemoglobin (HbA1C) >7.0%] and BMI < 35 kg/m(2) were included at five institutes between 2007 and 2010. The end point is T2DM remission, defined by fasting plasma glucose <110 mg/dl and HbA1C <6.0%. RESULTS Of the 200 patients, 172 (86%) underwent gastric bypass, 24 (12%) underwent sleeve gastrectomy, and the other 4 underwent adjustable banding. Laparoscopic access was used in all the patients. Gender (66.5% female), age (mean 45.0 ± 10.8), and HbA1C (mean 9.3 ± 1.9%) did not differ between the procedure among the groups. Until now, 87 patients had 1-year data. One year after surgery, the mean BMI decreased from 28.5 ± 3.0 to 23.4 ± 2.3 kg/m(2) and HbA1C decreased to 6.3 ± 0.5%. Remission of T2DM was achieved in 72.4% of the patients. Patients with a diabetes duration of <5 years had a better diabetes remission rate than patients with duration of diabetes >5 years (90.3% vs. 57.1%; p = 0.006). Patients with BMI > 30 kg/m(2) had a better diabetes remission rate than those with BMI < 30 kg/m(2) (78.7% vs. 62.5%; p = 0.027). Individuals who underwent gastric bypass loss more weight and had a higher diabetes remission rate than individuals who underwent restrictive-type procedures. Multivariate analysis confirmed that the duration of diabetes and the type of surgery predict the diabetes remission. No mortalities were reported and two (1.0%) patients had major morbidities. CONCLUSION Gastrointestinal metabolic surgery is an effective treatment for not well-controlled T2DM treatment. Diabetes remission is significantly higher in those with duration of diabetes less than 5 years and BMI > 30 kg/m(2).

Abstract
AIMS/HYPOTHESIS The aim of the study was to determine the transition rate and factors associated with the progression of normo- and low microalbuminuria to diabetic nephropathy (overt proteinuria). METHODS For 8 years we prospectively observed 1,558 Japanese patients with type 2 diabetes mellitus whose basal urinary albumin:creatinine ratio (UACR) had been measured as <17.0 mg/mmol at entry. The incidence of nephropathy (UACR >33.9 mg/mmol) was determined by measuring UACR twice a year. RESULTS Progression to nephropathy occurred in 74 patients. The annual transition rate was 0.67%, and was substantially higher for the low-microalbuminuric group than for the normoalbuminuric group (1.85% and 0.23%, respectively; hazard ratio for the low-microalbuminuric group 8.45, p < 0.01). The hazard ratio for an HbA(1c) of 7-9% or ≥9% was 2.72 (p < 0.01) or 5.81 (p < 0.01) relative to HbA(1c) <7.0%, respectively. In comparison with individuals with a systolic blood pressure (SBP) of <120 mmHg, the hazard ratios for patients with an SBP of 120-140 mmHg or ≥140 mmHg were 2.31 (p = 0.06) and 3.54 (p < 0.01), respectively. Smoking also affected progression to proteinuria (hazard ratio 1.99, p < 0.01). In contrast, 30.3% of the low-microalbuminuric group returned to normoalbuminuria (i.e. were in remission). CONCLUSIONS/INTERPRETATION These results suggest that if patients with type 2 diabetes mellitus are receiving treatment from diabetologists for hyperglycaemia and hypertension when they are in the early stages of nephropathy (i.e. normo- or low microalbuminuria), their rate of transition to proteinuria is considerably lowered, and that differentiating patients with low microalbuminuria from those with high microalbuminuria might be clinically useful.

Abstract
The emergence of Type 2 diabetes (T2D) in children and adolescents parallels the rising rates of childhood obesity. As a condition of impaired insulin sensitivity and relative insulin deficiency resulting in hyperglycemia, T2D has a complex underlying physiology that is reflected by the multiple approaches used to optimize medical care and prevent the myriad of diabetes-related complications. T2D diagnosed in children and adolescents represents a distinct and challenging condition to evaluate and treat. Here, we highlight the epidemiology, pathophysiology, risk factors, clinical presentation and diagnosis, treatment and public health impact of T2D in children and adolescents.

Abstract
In this paper, the islet autoimmunity status and relation to clinical characteristics, beta cell function and cardio-metabolic risk factors in young-onset Asian diabetic patients are evaluated at baseline. The study population consisted of 912 patients (from China, India, Malaysia and Singapore) with age 12-40 years and diabetes duration <12 months. Autoantibodies to glutamic acid decarboxylase (GADA) and tyrosine phosphatase (IA-2A), beta cell function and cardio-metabolic risk parameters were assessed. Among our young patient cohort, 105 (11.5%) patients were GADA and/or IA-2A positives (Ab +ve). Ab +ve patients were younger, leaner, had more severe hyperglycaemia and lower beta cell function. The frequency of metabolic syndrome was significantly lower in Ab +ve patients (27%) compared to Ab -ve patients (54%). However, a substantial proportion of patients in both groups of patients had atherogenic dyslipidaemia, hypertension and albuminuria (micro or macro). In our study cohort, only one in 10 Asian youth with new-onset diabetes had evidence of islet autoimmunity. At least 60% of Ab +ve and 50% of Ab -ve patients demonstrated classical features of type 1 and type 2 diabetes respectively. Regardless of autoimmunity status, the cardio-metabolic risk factors, in particular atherogenic dyslipidaemia, hypertension and albuminuria were common in our patients with young-onset diabetes.

Abstract
Type 1 diabetes mellitus (T1DM) commonly occurs in childhood or adolescence, although the rising prevalence of type 2 diabetes mellitus (T2DM) in these age groups is now being seen worldwide. Diabetic nephropathy (DN) develops in 15-20% of subjects with T1DM and in similar or higher percentage of T2DM patients, causing increased morbidity and premature mortality. Although overt DN or kidney failure caused by either type of diabetes are very uncommon during childhood or adolescence, diabetic kidney disease in susceptible patients almost certainly begins soon after disease onset and may accelerate during adolescence, leading to microalbuminuria or incipient DN. Therefore, all diabetics warrant ongoing assessment of kidney function and screening for the earliest manifestations of renal injury. Pediatric health care professionals ought to understand about risk factors, strategy for prevention, method for screening, and treatment of early DN. This review considers each form of diabetes separately, including natural history, risk factors for development, screening for early manifestations, and strategy recommended for prevention and treatment of DN in children and adolescents.

Abstract
BACKGROUND Body mass index (BMI) is associated with death in a V-shaped manner in general populations but it is unknown whether BMI or other risk factors also exhibit V-shaped relationships with death in type 2 diabetic patients. METHODS A prospective cohort of 7534 Chinese, type 2 diabetic patients enrolled since 1995 were censored on 30 July 2005. Spline Cox regression analysis with a stepwise algorithm (p < 0.05) was used to select predictors. Hazard ratio (HR) curves were used to explore the relationships, which were confirmed by standard Cox models. RESULTS 763 patients died during the 5.5 years of follow-up. BMI, high-density lipoprotein cholesterol (HDL-C) and white blood cell (WBC) count were related to all-cause mortality in a V-shaped manner. The nadirs of the risk curves were at 26 kg/m(2) for BMI, 1.15 mmol/L for HDL-C and 6.25 x 10(9) counts/L for WBC. The multivariate hazard ratio of BMI away from 26.0 kg/m(2) was 1.08; HDL-C, 1.06 per mmol/L for values less than the nadir and 6.97 per mmol/L for greater than the nadir; and WBC, 1.16 per 10(9) count/L for less than 6.25 x 10(9) and 1.47 for greater than the nadir. Respiratory and neoplastic deaths were the major contributors to the increased death in patients with low or high BMI. Neoplastic death was the major contributor to the increased death in those with low WBC. Genitourinary death was the major contributor to the increased death in those with low and high HDL-C. CONCLUSION BMI, HDL-C and WBC are associated with death in a V-shaped manner in type 2 diabetic patients.

Abstract
With the growing prevalence of childhood obesity and type 2 diabetes mellitus (T2DM) in youth, the challenge of cardiovascular disease risk management has entered the paediatric realm, affecting specialists, family physicians and allied healthcare professionals alike. Currently, there is little evidence to support optimal strategies for management of T2DM in youth and the associated cardiovascular complications. Physical activity plays a powerful role in the prevention and management of T2DM and cardiovascular disease in adults. This review will focus on the role of physical activity for the prevention of T2DM in youth and its associated cardiovascular complications. The first part describes the prevalence of cardiovascular risk factors in this cohort. The second part focuses on the role of physical activity in the prevention and management of T2DM in youth. Collectively, the limited intervention and observation studies published to date suggest that daily targets of 60-90 minutes of physical activity and less than 60 minutes of screen time (i.e. time spent in front of a television, computer or video games) are required for the prevention and management of T2DM in youth. Large-scale intervention studies are needed to determine the most effective physical activity strategies for the prevention and management of T2DM in youth.

Abstract
BACKGROUND Several studies have examined the role of cigarette smoking in the development of renal disease in human populations. However, there have been no systematic reviews on the evidence linking smoking with incident renal disease. METHODS We performed an evidence-based evaluation of peer-reviewed research published during 1966-2005, from a search of five databases, including Ovid MEDLINE and EMBASE. RESULTS Of the 28 studies that were reviewed, 11 were excluded from the final analysis due to poor methodological quality (n = 6), no reported risk estimate for the association between smoking and kidney disease (n = 3), inability to find a Japanese translator (n = 1), and duplicate cohort (n = 1). Seventeen studies were included in the final analysis; seven studies found an overall significant association between smoking and incident chronic kidney disease, and three studies found a significantly increased risk of chronic kidney disease in current smokers that was gender and/or dose related. An increased risk of developing chronic kidney disease among smokers was significantly associated with male gender (relative risk 2.4, 95% confidence interval 1.2-4.5), >20 cigarettes smoked/day (odds ratio 1.51, 95% confidence interval 1.06-2.15, and relative risk 2.3, 95% confidence interval 1.2-4.3), and smoking >40 years (odds ratio 1.45, 95% confidence interval 1.00-2.09). A pooled estimate of the relative risk (meta-analysis) was deemed inappropriate due to the heterogeneity in methodologies utilized by the different studies. CONCLUSIONS This comprehensive review reveals overall evidence for current cigarette smoking as a risk factor for incident chronic kidney disease. Further investigation is needed to more carefully examine the strength of the association between cigarette smoking and incident kidney disease.

Abstract
With the increase in prevalence of type 2 diabetes mellitus in adolescents, a rise in incidence of secondary comorbidities--including hypertension, hyperlipidaemia, nephropathy, and retinopathy--is anticipated. Furthermore, findings of studies in young adults have suggested that the development and progression of clinical complications might be especially rapid when the onset of type 2 diabetes is early, raising the possibility of a serious public-health challenge in the next few decades. To date, reports of the epidemiology and natural history of secondary complications specifically in adolescents with type 2 diabetes have been scarce. Yet, we must begin to understand the extent of the coming challenge. To this end, we have reviewed reports on acute and long-term comorbidities associated with type 2 diabetes in young people and have looked at mounting evidence that this group could be at increased risk for development of early complications.

Abstract
The metabolic syndrome is complicated by nephropathy in humans and rats, and males are more affected than females. We hypothesized that female rats had reduced expression of glomerular oxidized low-density lipoprotein (oxLDL) receptor 1 (LOX-1), attendant glomerular oxidant injury, and renal inflammation. Three groups, obese males (OM), obese females (OF), and lean males (LM) of first-generation (F(1)) hybrid rats derived from the Zucker fatty diabetic (ZDF) strain and the spontaneous hypertensive heart failure rat (SHHF/Gmi-fa) were studied from 6 to 41 weeks of age. OM had severe renal oxidant injury and renal failure. Their glomeruli expressed the LOX-1, and exhibited heavier accumulation of the lipid peroxide 4-hydroxynonenal (4-HNE). OM had compromised mitochondrial enzyme function, more renal fibrosis, and vascular leakage. Younger LM, OM, and OF ZS (ZDF/SHHF F(1) hybrid rat) rats, studied from 6 to 16 weeks of age, showed that unutilized renal lipids were comparable in OM and OF, although young OM had worse nephropathy and inflammation. In conclusion, glomerular LOX-1 expression is coupled to deposits of 4-HNE and glomerulosclerosis in OM. We presume that LOX-1 enhances glomerular uptake of oxidized lipids and renal inflammation, causing greater oxidant stress and severe glomerulosclerosis. In OF, renal protection from lipid oxidants appears to be conferred by blunted glomerular LOX-1 expression and renal inflammation.

Abstract
BACKGROUND/OBJECTIVES The rising prevalence of pediatric type 2 diabetes mellitus (DM2) and non-adherence to diabetes regimens pose challenges to obtaining optimal control. This study evaluated factors that may impact glycemic control (HbA1c): age, Tanner stage, body mass index (BMI), total daily insulin (TDD), metformin dose (MET), activity level, frequency of clinic visits and adherence. METHODS One-year data from 72 patients (ages 8.6-17.8 years) were collected retrospectively. From that sample, 57 patients who continued to attend clinic for the entire year were assessed and divided into optimal and suboptimal HbA1c control groups. RESULTS All factors measured were similar in the two groups, except for lower initial and 1.0-year HbA1c, TDD, and rates of missing MET and insulin in the optimal HbA1c control group. CONCLUSIONS Initial glycemic status and adherence rate predicted metabolic control at one year. Early identification of DM2 may improve metabolic outcome, which may improve medical regimen adherence.

Abstract
Type 2 diabetes (T2DM) is now a pediatric disease. As in adults, it disproportionately affects ethnic and racial minorities, including Hispanics. The preponderance of Hispanics in south Texas are of Mexican American (MA) heritage. Over the past 16 years, we have accumulated a large cohort of children with diabetes. We have noted distinct differences in numerous parameters between MA children with T2DM and those with type 1 diabetes (T1DM). In order to explore these observations, we have reviewed the records of all children diagnosed with diabetes (n = 669) during the 9 years between January, 1990 and December, 1998 and seen by our pediatric diabetes group. In this cohort were 329 MA, 287 non-Hispanic whites (EA) and 53 African Americans. Compared to EA children with T1DM, MA children were more likely to have a parent with diabetes, to be hospitalized at the time of diagnosis and to lack health insurance. The differences between MA children with T1DM and T2DM were significant: specifically, children with T2DM were more likely to be female and pubertal with a body mass index >25 kg/m(2) and have acanthosis nigricans. Slightly more than 2/3 of the MA children with T2DM had at least one parent already diagnosed with T2DM. Less than 1/3 of the children with T2DM required hospitalization at the time of diagnosis and only a 1/4 have private health insurance. Over this 9-year interval, the apparent incidence of diabetes almost tripled in south Texas with the great majority of that increase due to the increasing numbers of children with T2DM.

Abstract
Understanding reasons for the neglect of foot screening during the annual review of people with diabetes enables the development of solutions for this omission. This study explores the reasons within the context of health care delivery systems in terms of the professional, social, political and economic aspects of this screening. Information was obtained through reviewing publications on diabetic foot and health care reform. The omission of annual foot examination for people with diabetes is attributed to the nature of diabetes-related foot problems, people with diabetes, health care professionals and the current structure of health care delivery systems. Increasing the adherence to foot screening for those with diabetes requires short- and long-term strategies. Short- and long-term strategies for reminding patients and staff about foot screening are suggested.
